If your vehicle should become stuck in deep snow or mud, try switching
the AdvanceTrac
威
with RSC system off by pressing the AdvanceTrac
威
with RSC button momentarily. This will allow your tires to “dig” for
traction.
If the AdvanceTrac
威
with RSC system is activated excessively in a short
period of time, the brake portion of the system will disable to allow the
brakes to cool down. In this situation, Traction Control will use only
engine power reduction to help control the wheels from over-spinning.
When the brakes have cooled down, the system will again function
normally. Anti-lock braking, RSC and ESC are not affected by this
condition and will function normally during the cool-down period.
If the vehicle is stuck in snow or mud or when driving in deep sand,
switching off the AdvanceTrac with RSC system may be beneficial so the
wheels are allowed to spin. If your vehicle seems to lose engine power
while driving in deep sand or very deep snow, switching off the
AdvanceTrac with RSC stability enhancement feature will restore full
engine power and will enhance momentum through the obstacle.
During Traction Control events the “sliding car” icon in the instrument
cluster will flash momentarily.
Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) with RSC system may enhance
your vehicle’s stability during adverse maneuvers.
The AdvanceTrac
威
with RSC system helps the driver maintain steering
control. AdvanceTrac
威
with RSC will attempt to correct the vehicle
motion by applying brake force at individual tires and, if necessary, by
reducing engine power.
During Electronic Stability Control events the “sliding car” icon
in the
instrument cluster will flash momentarily.
Driving maneuvers which may activate AdvanceTrac
威
with RSC system
include:
•
Taking a turn too fast.
•
Maneuvering quickly to avoid an accident, pedestrian or obstacle.
•
Driving over a patch of ice.
•
Changing lanes on a snow-rutted road.
•
Entering a snow-free road from a snow-covered side street, or vice
versa.
•
Entering a paved road from a gravel road, or vice versa.
